The upper top plate 18 is provided with a detachably fixed line cover plate 19. The interior of the mounting plate unit 11 is provided with a wire trough and a guide rail. Through the arrangement of the internal mounting plate 9 and the rear sealing plate 10 and other structures, the mounting plate is installed close to the rear sealing plate 10, which increases the internal space of the cabinet, optimizes the arrangement of the track and wire trough in front of the internal mounting plate 9, and adds an internal mounting plate 9 to install electrical components, which can ensure the installation of all electrical components and realize a TCR control device that can be maintained in one direction from the front.

[0025] See also Figure 1-4 The base unit 8 is provided with a wire entry bottom plate 23, and a knock-out hole 24 is provided on the base unit 8. By setting the structures such as the wire entry bottom plate 23 and the knock-out hole 24, the original lower wire entry bottom plate 23 is retained, and the wire entry hole is modified into the knock-out hole 24. When the wire entry method is not used or the upper wire is entered but there is a gap, the cover plate 19 can be used to close the wire entry hole or clamp the cable to prevent dust from entering, so that the device can meet the upper and lower wire entry requirements at the same time.

[0026] See also Figure 1-4 A mounting base 20 is welded to the bottom of the top plate unit 1, a bridge fixing plate 21 is welded to the bottom of the upper top plate 18, and an optical fiber mounting bridge 22 is fixedly connected between the bridge fixing plate 21 and the mounting base 20. A mounting plate unit 11 is installed inside the rear sealing plate 10, and an upper fixing part 25 and a middle fixing part 26 are provided inside the mounting plate unit 11. The swing door 4 is set as a hinge panel 3, and an internal mounting plate 9 is installed inside the hinge panel 3.

The bottom of the welding unit 2 is provided with a grille panel 6 and a grille mounting plate 13.

[0027] The specific implementation process of the present invention is as follows: in order to optimize the design of the TCR control device, first, the rear maintenance space is abandoned, and a new fixing part is designed so that the mounting plate can be installed close to the rear sealing plate 10. This improvement significantly increases the available space inside the cabinet and improves space utilization. Secondly, the track and wire duct layout in front of the internal mounting plate 9 is optimized, and the bus ducts originally located at the left and right ends are cancelled. Instead, the steel network bridge frame on the side of the cabinet is used for wiring. This improvement not only simplifies the line layout, but also improves the reliability and maintainability of the wiring. In the design of the swing door 4, the original empty panel is changed to a hinged opening and closing panel. This design makes the opening and closing of the panel more convenient and quick. At the same time, a built-in mounting plate is added inside the panel for installing electrical components. All electrical components can be installed and maintained in one direction on the front side, which greatly improves the convenience of maintenance.

[0028] Furthermore, the original lower wire entry bottom plate 23 is retained, and the wire entry hole is improved. The wire entry hole is modified into a knock-out hole 24, which can ensure the bottom sealing when the lower wire entry is not selected. At the same time, the upper wire entry hole is added by changing the layout of the top plate, and a pull-out wire entry cover 19 is configured. When a certain wire entry method is not used or there is a gap in the upper wire entry, the pull-out cover 19 can be used to close the wire entry hole or clamp the cable, effectively preventing dust from entering the cabinet, making installation more convenient.
